Double-Ace Racing Products introduces the AA Engines 67/80/90 Cable Collet. It comes with both stainless steel inner collet and stainless steel nut with an 8mm thread. It fits 1/4" shaft cables as well as MAC 67, CMB 67, 80, and 90 and the Kalistratov 67, 82, and 90 Engines. They will also fit the AA .67 and .84. They have little or no machining flash as they were cleaned before packaging. This is the big difference between the A/A cable nuts and the competition. The competition's cable nuts have quite a bit of flash left on the collets. Flash forces the collet out of alignment and creates vibration as the cable absorbs the changes of direction while rotating. These items are machined in the USA with the same quality as Boeing, Ratheon, and Lockheed Martin so you can expect exceptional quality, workmanship and performance.
